The PCM510xA devices are a family of monolithic CMOS-integrated
circuits that include a stereo digital-to-analog converter and additional support circuitry in a
small TSSOP package. The PCM510xA devices use the latest generation of TIs
advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance
to clock jitter.
Using Directpath™ charge-pump
technology, the PCM510xA devices provide 2.1-VRMS ground
centered outputs, allowing designers to eliminate DC blocking capacitors on the output, as well as
external muting circuits traditionally associated with single-supply line drivers.
The integrated line driver surpasses all other charge-pump based line drivers by
supporting loads down to 1 kΩ per pin.
The integrated PLL on the device removes the requirement for a system clock (commonly
known as master clock), allowing a 3-wire I2S connection and reducing
Intelligent clock error and PowerSense undervoltage protection utilizes a two-level mute
system for pop-free performance.
Compared with many conventional switched capacitor DAC architectures, the
PCM510xA family offers up to 20 dB lower out-of-band noise, reducing EMI and
aliasing in downstream amplifiers/ADCs, measured from the traditional 100-kHz OBN measurements to 3
